Citrion measures who the AI assistants actually cite.
Every EZ Web AI visibility audit is produced by Citrion, the measurement instrument we built and run ourselves. It records answers from six engines, at least two runs per prompt and three on a full audit. This page says what it records, what comes out the other end, and what it is not.
Free. The audit is Citrion, run on your site, read by a person before you get it.
Real answers, in real sessions, on five assistants.
Citrion asks the questions your buyers ask inside ChatGPT, Perplexity, Claude, Grok, and Copilot, and keeps the whole answer: the text, the sites it links to, and the search queries the assistant wrote for itself before answering. Nothing on the observed side is reconstructed from an API after the fact.
Google AI Overviews are measured where we can observe them and modeled where we cannot. Every Google number in a report says which, and a modeled number is never presented as an observation.
One score, and the names behind it.
The share of recorded answers in which your business appeared, by name or by link. Computed from the answers, never estimated.
A leaderboard of the sites the assistants sent your buyers to instead, with the share each one holds. Usually one site holds a surprising amount of it.
Every answer that named you, read for favorability, with the drawbacks quoted word for word. The sentence an assistant attaches to your name is the one a lead reads before signing.
What to open, publish, and earn, in order, starting with anything that keeps the assistants from reading your site today.
Every number carries an evidence tier, published at how we measure AI visibility. Where a sample is too small to support a number, the report says so instead of printing one.

Citrion is not a dashboard you log into, and we do not sell it on its own. It exists to produce the audit and to re-measure the same questions every month for clients on a plan, so the score moves against the same yardstick it started on.
It does not guarantee a citation. No instrument can, and attribution from an AI answer to a signed customer is still unsolved. Citrion measures visibility, which is the input you can actually change.
Platforms such as Profound and Evertune measure well and hand you a queue of recommendations. Citrion's output goes to the people who then do the work: the rewrites, the technical fixes, and the new pages, each reviewed by an expert before it ships. The protocol is public and the tooling stays private, so anyone can follow the recipe by hand and hold any other tool to the same standard.
